To which homologous series, Ethanol belongs to?

Open in App

Solution

A homologous series is a group of compounds that share the same general formula and have similar chemical characteristics.
Alcohols are hydrocarbons that have one or more hydroxyl groups ( $- OH$ ) linked to a saturated Carbon atom.
They all contain the functional group –OH, which is responsible for alcohol's characteristics. The word 'ol' appears at the end of the IUPAC names of alcohol.
Therefore, Ethanol ( $C_{2} H_{5} OH$ ) belongs to Alcohol's homologous series.
